My mom used to make this mix when we were kids. It's simple and versitile, freezes easily and you can add other ingredients to jazz it up.
2 cups cooked rice
1/2 cup salsa
1/2-1 block cream cheese (depending on how thick you want it)
shredded cheese to taste (whatever you have on hand)
4 or more cooked chicken tenderloins, or whatever cooked chicken you have on hand
Mix the ingredients together and serve as burritos.
Sometimes I add 1/2 cup peas or 1/2 cup corn, or both to the mix. It also tastes pretty good as a sandwich mix, or served sloppy-joe style over hamburger or hot dog buns.
Mix a double batch and freeze some-it thaws beautifully.
